Description

If an invalid UUID is given to the vminfo operation of VBoxManage snapshot, the error message implies that a VM name must be given. For example, if 123-f00d-baaa-baaa-baaa is the correct UUID of a Machine, but 456-dead-f00d-600d-600d is not a valid snapshot UUID, this happens:

This is probably only really a problem for those learning the VBoxManage tool, who may reach the conclusion that UUIDs are not actually accepted by this operation. It would be better to rephrase the error message to something like "Could not find a snapshot with name or UUID '456-...".
